HIGH Summary
An issue was discovered in Kentico 12.0.x before 12.0.15, 11.0.x before 11.0.48, 10.0.x before 10.0.52, and 9.x versions. Due to a failure to validate security headers, it was possible for a specially crafted request to the staging service to bypass the initial authentication and proceed to deserialize user-controlled .NET object input. This deserialization then led to unauthenticated remote code execution on the server where the Kentico instance was hosted.

Metasploit
| description | This module exploits a vulnerability in the Kentico CMS platform versions 12.0.14 and earlier. Remote Command Execution is possible via unauthenticated XML requests to the Staging Service SyncServer.asmx interface ProcessSynchronizationTaskData method stagingTaskData parameter. XML input is passed to an insecure .NET deserialize call which allows for remote command execution. |
